Darren,
I understand your concern but once you get to know us here, you will feel a bit more secure.
Believe me, I am as security conscious as they come, but once I realized that my info was safe with the Avast team, it bothered me no longer.
They would never use it in a harmful way, or share it outside of Alwil.
Not only is Avast Antivirus great…
So are the people connected with it! ;D
